Novel antenna technology lowers PCB resonance, enabling easier provision of multiband performance, greater flexibility in antenna design and, in some cases, improved SAR value management.
Fractal antenna technology pioneer Fractus has developed an antenna technology which lowers PCB resonance, enabling easier provision of multiband performance, greater flexibility in antenna design and, in some cases, improved SAR value management All of these factors are critical for the development of next generation handset and mobile devices

Chip antenna boasts ultrawideband coverage
A new chip-scale ultrawideband antenna combines an omnidirectional radiation pattern and high efficiency level to deliver the largest bandwidth possible.
Fractus' proprietary BandXpand technology is linked to the antenna on one side of the circuit board.
This shapes the current electromagnetic path, enabling resonance at lower frequencies, thus making it easier to have additional frequencies with broader bandwidth in both mobile handsets and other wireless devices.
Antenna designers can then fine-tune frequencies to deliver improved lower frequency performance and multi-band functionality.
An antenna designer could, for example, develop a single quad-band antenna with GSM 900/1800 and CDMA 800/1900 capabilities without the need for a switchplexer, and a separate UMTS antenna, isolated from the quad-band antenna by 12dB - producing a device that could handle two way voice calls anywhere in the world at the same time as downloading a multimedia file.
"Fractus BandXpand provides another tool for mobile designers to enable smaller, high capability handsets and devices, so antenna design can conform even more to the mechanics required by device OEMs and ODMs", said Fractus CTO Dr Carles Puente.
"This technology means antenna and device designers, working together, have greater flexibility in terms of antenna and device performance than ever before".
Fractus has developed demonstrators of its BandXpand technology which are available for demonstration to key clients.
